"There's a person or persons out there who could very well commit another murder," Cuevas said.

Sladewski's burning body was discovered in a Miami dumpster last Sunday night. Her body was so badly burned it took another two days and dental records to identify her. Police do not believe she was burned alive, but have not released a cause of death.

Surveillance video from a trendy South Beach, Miami nightclub shows Sladewski leaving Club Space at 7:21 a.m. on the day she was killed, according to police.

Sladewski's boyfriend, Kevin Klym, 34, had been kicked out of the club 20 minutes earlier after a shouting argument with Sladewski, according to a missing persons report. The pair had been been partying in Miami since a New Year's Eve Lady GaGa concert.
